The mighty Ford Mustang Boss 429 served to homologate Ford’s 429 CI “Semi Hemi” engine for NASCAR competition. Ford commissioned the building of the Boss 429 to Kar Kraft, whose Brighton, Michigan, facility converted 428 Cobra Jet and Super Cobra Jet Sportsroof models with extensive modifications to the front suspension, moving the shock towers and inner fenders to make room for the engine block and exhaust manifolds. The battery was relocated to the trunk and a special sway bar added at the rear to help balance the 429’s heft. The result was one of the rarest and most powerful Mustangs ever built and today one of the most highly prized muscle cars from that magnificent era. Built on September 29, 1969 and delivered new on November 11, 1969 by Hull Dobbs Ford in Memphis, Tennessee, this 1970 Boss 429, KK #2192, is powered by a correct Boss 429 engine from KK #1864 backed by a 4-speed manual transmission and 3.91 Traction-Lok rear end. Finished as original in Grabber Blue with a White interior, it also features the Boss-9 specific Competition Suspension, power steering and front disc brakes, Deluxe Décor Group and AM radio. It received a rotisserie restoration completed in 2001 and in 2009 was refreshed to MCA guidelines by highly respected East Coast Mustang restorer Hunter Williard. In addition to its highly detailed engine bay – including the correct pollution control system – the car boasts all the correct chalk marks, overspray and paint dabs as delivered in 1970.
